Unless you are willing to change your elements more frequently, do not use salts in an electric kiln. My friend , Russel Fouts , fires saggaars in electric kiln and has published articles about it. he does not use salts. Please google his articles. One is called "yes you can"
it was in Pottery Making illustrated. his website is mes-Potes
I fire mine in my raku kiln with gas.
the saggaars are sealed.
russel fires in his electric. has not change his elements in 15 years. Currently he is using a hard brick saggar and adds charcoal inside.
he has written about using aluminum foil to wrap pieces rather than using the traditional saggar idea. I think you would benefit to read some of his ideas.

i get it... thank you for your help

your descriptions are very nice and understandable, I'll do it surely... but in the last part, I have electric kiln, so the source of heat is scattered through all sides, how should I deal with this ?
thank you

put the oxides in the sawdust and not on the bottom of the saggar. Mix the oxides with salt.put your pot on a chunk of brick above the combustibles.
You hold the temperature by cutting back on your fuel and watching it with a pyrometer.
The cap of the saggar should be tight.

my saggar is a vase 40cm hight and 3ocm diameter, 2cm thickness..... i lay oxides at the bottom and set my works and put sawdust between them, i didn't use salt...
do i use salt top of saggar????
do i put oxides in the special place or i can pour at the bottom of saggar and top of the works?????
do i hold in temperature?
if the cap of saggar is not closed correctly, may it cause any problem????
thank you
